The Studies Of Question On Induction Validity

The inductive logic is a branch discipline , development of its prospect is extremely vast in logic discipline. Induction is a kind of method of the problem coming to resolve reality using the inductive logic. Induction has the important recognizing ability in study of science and the daily life. The classical allusion inductive logic has got through several thousands of years development and has already transited to modern inductive logic in 19 centuries till 20 centuries. The inductive logic is probed and improved and perfected by a lot of scholars and have become a logic discipline middle important branch now. Induction included complete induction , incomplete induction and the method seeking cause and effect. United Kingdom phlosopher David Hume questions induction, He has brought forward a question: How can debut a full name judging from limited instance? Can we use induction to push from the known number to really unknown? Then, is the Nature law existence originally or imposed on by us? Now, the induction validity has accepted challenge.We think that induction has arrived at the irreplaceable effect in getting up for human being probes the Nature profound mystery and human society self's law, therefore, we are necessary wielding the materialism principle and doubt that doctrine and agnosticism combat, makes the induction validity get the cogent certificate. And be necessary discussing the tactics that induction wields rationally, for instance, handling in reality and discovering in science.The thesis divides into three parts together. Part I has been recollected induction validity problem, has analysed David Hume wrong place of opposing induction , having drawn forth induction has been one kind of effective scientism. Part II analyses the induction validity mainly preserving degree from theory and practice. Important induction function of the scientific exploration and science innovation are also expounded. then demonstrate the validity starting with the induction operation angle, then finally look into the induction and put the possibility of guiding induction principle. And Part III is some tactics of guaranting induction be applied or used universally and have discussed a series of effective method and measure to the induction in scientific discovery and the certification of hypothesis.
